Jasmonic acid signaling in plants: regulatory mechanisms in development and stress responses.

Jasmonic acid signaling via the COI1-JAZs-MYCs complex regulates seed germination, root elongation, and leaf senescence in plants.

• Why it matters: Understanding JA's regulatory mechanisms is crucial because it influences plant development and stress responses, areas that previously lacked comprehensive review.
• What they did: The review synthesizes recent advances in JA biosynthesis and signal transduction, focusing on the key regulatory complex and its role in development and abiotic stress responses.
• The result: Findings highlight JA's coordination with other hormones and genes in stress responses, supporting future applications to enhance crop resilience and productivity.
